Handling multiple IRPs in 1 dispatch function?

NTFSD

Hi,
Is it possible to complete 2 IRPs in one dispatch function?

If I receive a specific IOCTL in the driver, can I first mark it pending,
and then return data for it in the dispatch function for read. I plan to
save the original IRP in an array (or custom queue) and then in the
dispatch function for read, call IoCompleteRequest for both the saved IRP
as well as the current one and return STATUS_SUCCESS?

Also can these 2 IRPs be from different user processes?

Thanks in advance,
Jagannath

Sure, why not.
